5.3. Maintenance of axle bearings
After first 500 km of driving you must check the play of axle hub bearings. To check the
play of hub bearings raise the axle from the ground by means of proper jack and
release the brake. Put one or two iron bars between the tyre and the ground and check
the movement. If wheel shows the excessive play it is necessary to readjust the
bearings. In order to regulate the hub bearings you must perform the following actions:

Actuate parking brake of the tractor.
Raise the wheels of trailer by proper jack.
Remove the hub cap.
Remove the split pin of castle nut.
Tighten the castle nut until the hub hardly turns.
Unscrew the castle nut by 1/3 or revolution until the nearest groove for the split
pin.
Secure the castle nut with split pin.
Mount the hub cap.
After bearing regulation the wheel should rotate smoothly without any jams. During
